1000W ATX 3.0 power supply

This fully modular unit delivers 1000 W from a single +12 V rail and meets the Intel ATX 3.0 design guide. It includes a native 16-pin connector rated for 600 W to support PCIe 5.0 graphics cards. Japanese capacitors and a 120 mm hydraulic bearing fan complete the build.

Suits high-end GPU builds; skip for modest systems

Builders pairing a modern 600 W-class graphics card with a powerful CPU will benefit from the 200 % total power excursion allowance and 70 % efficiency at low load. Systems targeting mid-range or entry-level GPUs do not need this headroom and can choose a lower-wattage unit.

1000 W capacity with 600 W GPU headroom

The single-rail design comfortably feeds a 600 W graphics card plus CPU and peripherals while staying within the 80 Plus Gold 90 % typical-load efficiency mark. Protection circuits cover over-voltage, over-power, short-circuit, under-voltage, over-current and over-temperature events. Beyond the rated 1000 W the unit reaches its limit.

Questions about this item

Do I need an ATX 3.0 compatible motherboard to use this 1000W unit?

No. The PSU follows the ATX12V form factor and includes a 20+4-pin main connector, so it works with standard ATX motherboards. The ATX 3.0 certification means it can handle 200% power excursions and 70% low-load efficiency, but it does not require a new board.

Will the four 6+2-pin PCIe connectors and the 16-pin cable power an older graphics card that only has 8-pin sockets?

Yes. Each 6+2-pin plug can be used as a straight 6-pin or an 8-pin connector, and the native 16-pin cable is only needed for PCIe 5.0 cards rated up to 600W. Older GPUs simply use the 6+2-pin leads.

How can I confirm the fan is running in its low-noise mode after I build the system?

The 120mm hydraulic-bearing fan spins at a reduced speed under light loads and ramps up as power draw increases. You can hear the change in acoustic level when the system moves from idle to a heavy workload, confirming the smart fan curve is active.
